Can someone please assist in following:
I have to assert array with x elements (usually not more than 6 or 7) and if there is any duplicates, it has to throw error - or step to fail. So far I did the following:
Cypress.Commands.add('addTextElementIntoArray', (list) => {
var textsArray = []
cy.xpath(list).each(($el) => {
const text = $el.text().replace(' ', '')
textsArray.push(text)
cy.log(text)
})
})
Tried this solution: Find duplicates, but it does not work in Cypress. How can I solve this? Thank you in advance
Found solution, and here it is:
Cypress.Commands.add('addTextElementIntoArray', (list) => {
var textsArray = []
var non_unique = []
cy.xpath(list)
.each(($el) => {
const text = $el.text().replace(' ', '')
textsArray.push(text)
cy.log(text)
non_unique = textsArray.filter((item, i) =>
textsArray.includes(item, i + 1)
)
})
.then(() => {
expect(non_unique.length).equal(0)
})
})
Using the answer from the linked question in Cypress,
Cypress.Commands.add('listHasNoDuplicates', (list) => {
cy.xpath(list)
.then($els => [...$els].map(el => el.innerText.trim()))
.then(texts => {
const unique = new Set(texts)
expect(texts.length).to.eq(unique.size)
})
})
})
